OK, I should've remembered that was listed in the Review forums... Thanks Roy.
I would guess that, in an e2e for example, it would allow brighter much more consistent output than the low output lamp (MN02). I wonder if an R2 and a DB400 would be brighter than the MN02...
EDITED: Has anyone ever done Wizard 400 runtime plots? When in buck mode will it also have the nice super flat output?
